A 401(k) remains one of the most powerful retirement savings tools available to American workers, and the annual contribution limits determine how much of your pay you can shelter from taxes each year. For 2026, the IRS increased the limits again, and new rules from the SECURE 2.0 Act now affect how some older, higher-earning workers make catch-up contributions. This guide covers the 401k contribution limits for 2026, explains each type of limit, and offers practical ways to decide how much to save.

The 2026 401(k) limits at a glance
The IRS announced the 2026 figures in Notice 2025-67:
| Limit | 2025 | 2026 |
|---|---|---|
| Employee elective deferral | $23,500 | $24,500 |
| Catch-up contribution, age 50+ | $7,500 | $8,000 |
| “Super” catch-up, ages 60 to 63 | $11,250 | $11,250 |
| Total contributions from all sources (415(c) limit) | $70,000 | $72,000 |
| Roth catch-up wage threshold (prior-year FICA wages) | n/a | $150,000 |
The employee deferral limit also applies to 403(b) plans, most governmental 457 plans, and the federal Thrift Savings Plan.
Employee elective deferral limit: $24,500
The elective deferral limit is the maximum you can contribute from your paycheck in a year, whether as traditional pre-tax contributions, Roth contributions, or a mix. For 2026 that limit is $24,500.
The limit is per person, not per plan. If you change jobs midyear or have two 401(k) plans, your combined deferrals across all plans cannot exceed $24,500 (plus any catch-up you are eligible for). Each employer tracks only its own plan, so it is up to you to avoid going over. If you exceed the limit, contact your plan administrator promptly to have the excess returned, generally by April 15 of the following year, to avoid double taxation.
Catch-up contributions for age 50 and older
If you turn 50 or older at any point during 2026, you can contribute an additional $8,000, for a total of $32,500 in employee deferrals. You do not need to be 50 on January 1; reaching 50 by December 31 is enough.
The super catch-up for ages 60 to 63
SECURE 2.0 created a higher catch-up limit for workers who are 60, 61, 62, or 63 at the end of the year. For 2026, that amount is $11,250, allowing total employee deferrals of up to $35,750. Once you turn 64, you return to the regular age-50 catch-up amount. Plans are not required to offer the super catch-up, so confirm that yours does.
The new Roth catch-up rule for higher earners
Starting in 2026, SECURE 2.0 requires certain higher earners to make catch-up contributions on a Roth (after-tax) basis. If your FICA wages from the employer sponsoring the plan were more than $150,000 in 2025, any catch-up contributions you make in 2026 must go into the Roth portion of the plan.
Key points:
- The rule applies only to catch-up contributions, not to your regular $24,500 deferral, which can still be traditional pre-tax.
- The threshold is based on Social Security (FICA) wages from that employer in the prior year, shown in Box 3 of your W-2.
- If your plan does not offer a Roth option, affected employees may not be able to make catch-up contributions at all.
- Self-employed people and partners without FICA wages from the plan sponsor are generally not subject to this requirement.
Roth catch-ups lose the upfront tax deduction but grow tax-free and can be withdrawn tax-free in retirement if requirements are met.
The total contribution limit: $72,000
The 415(c) limit caps the total of all contributions to your account in a year, including your deferrals, employer matching, employer profit-sharing, and any after-tax contributions. For 2026 the limit is $72,000. Catch-up contributions are added on top, so a 50-plus worker could theoretically reach $80,000, and a worker aged 60 to 63 could reach $83,250.
This higher total matters mainly for people whose plans allow after-tax contributions beyond the regular deferral, sometimes used for a strategy called the “mega backdoor Roth,” and for self-employed people with a solo 401(k).
Employer matching contributions
Employer matches do not count toward your $24,500 employee limit, but they do count toward the $72,000 total. Common match formulas include 50% of contributions up to 6% of pay or a dollar-for-dollar match up to a set percentage. Because a match is effectively additional compensation, contributing at least enough to receive the full match is widely considered a priority.
Also check your plan’s vesting schedule. Your own contributions are always 100% yours, but employer contributions may vest over several years. Leaving a job before you are vested can mean forfeiting part of the match.
Under SECURE 2.0, employers may also allow matching contributions based on qualified student loan payments, and they may let employees choose to receive matching contributions as Roth contributions. These features are optional for employers.
Traditional vs Roth 401(k) contributions
Many plans offer both options:
- Traditional 401(k): contributions reduce your taxable income now; withdrawals in retirement are taxed as ordinary income.
- Roth 401(k): contributions are made after tax; qualified withdrawals, including earnings, are tax-free.
The better choice often depends on whether you expect your tax rate to be higher now or in retirement. Since OBBBA made the current tax brackets permanent, some of the uncertainty about rates rising in 2026 has been removed, but future rates can always change. Splitting contributions between both types can provide flexibility in retirement. Roth 401(k) balances are no longer subject to required minimum distributions during the owner’s lifetime, starting in 2024.
How much should you contribute?
There is no single right answer, but these guidelines help:
- Capture the full employer match first. Missing it leaves compensation on the table.
- Build an emergency fund. Money in a 401(k) is generally subject to income tax and a 10% penalty if withdrawn before age 59½, with some exceptions.
- Raise your rate gradually. Many plans offer automatic annual increases. Raising contributions by one percentage point each year, or when you get a raise, is less noticeable than a large jump.
- Consider the maximum if you can. Maxing out is easier for higher earners, but any increase adds up over decades because of compound growth.
- Coordinate with an IRA and HSA. In 2026 you can also contribute $7,500 to an IRA ($8,600 at 50 or older) and, if eligible, up to $4,400 or $8,750 to an HSA.
Divide the limit into paychecks
To max out at $24,500 with 26 biweekly paychecks, you would contribute about $942 per paycheck. With 24 semimonthly paychecks, it is about $1,021. Some plans “true up” the match at year-end, but others match only per paycheck, so front-loading contributions early in the year can cost you match dollars. Check your plan’s rules before maxing out early.
Other workplace plans
- 403(b) plans share the same $24,500 deferral limit. Some offer an extra catch-up for long-tenured employees of qualifying organizations.
- Governmental 457(b) plans have a separate $24,500 limit, so a worker with both a 403(b) and a 457(b) may be able to contribute to both.
- SIMPLE IRAs have a lower 2026 limit of $17,000, with a $4,000 catch-up in most plans.
Frequently Asked Questions
What is the 401(k) contribution limit for 2026?
Employees can defer up to $24,500 in 2026. Those 50 and older can add $8,000, and those aged 60 to 63 can add $11,250 instead.
Does my employer match count toward the $24,500 limit?
No. Employer contributions count toward the $72,000 total limit, not the employee deferral limit.
Who must make Roth catch-up contributions in 2026?
Employees whose 2025 FICA wages from the plan sponsor exceeded $150,000 must make any 2026 catch-up contributions as Roth contributions.
Can I contribute to a 401(k) and an IRA in the same year?
Yes. The limits are separate. However, if you are covered by a workplace plan, your ability to deduct traditional IRA contributions depends on your income.
What happens if I contribute too much across two jobs?
Contact one of your plan administrators to remove the excess and its earnings, generally by April 15 of the following year. Excess deferrals left in the plan can be taxed twice.
Is the super catch-up available at age 64?
No. The higher catch-up applies only to participants who are 60, 61, 62, or 63 at the end of the year.
The bottom line
The 401k contribution limits for 2026 give workers more room to save: $24,500 in employee deferrals, $8,000 more at 50 or older, and $11,250 more from ages 60 to 63. Higher earners should prepare for the new Roth catch-up requirement. Whatever your income, capturing the full match and raising your savings rate steadily can do more for your retirement than any single year’s limit.
